Abstract

BACKGROUND
The aim of this study was to investigate the clinical significance of Quilty lesions in endomyocardial biopsies (EMBs) of cardiac transplantation patients.
METHODS
A total of 1190 EMBs from 117 cardiac transplantation patients were evaluated histologically for Quilty lesions, acute cellular rejection, and antibody-mediated rejection. Cardiac allograft vasculopathy was diagnosed by computed tomography coronary angiography. Clinical information, including the patients' survival was retrieved by a review of medical records.
RESULTS
Eighty-eight patients (75.2%) were diagnosed with Quilty lesions, which were significantly associated with acute cellular rejection, but not with acute cellular rejection ≥ 2R or antibody-mediated rejection. In patient sdiagnosed with both Quilty lesions and acute cellular rejection, the time-to-onset of Quilty lesions from transplantation was longer than that of acute cellular rejections. We found a significant association between Quilty lesions and cardiac allograft vasculopathy. No significant relationship was found between Quilty lesions and the patients' survival.
CONCLUSIONS
Quilty lesion may be an indicator of previous acute cellular rejection rather than a predictor for future acute cellular rejection.
